Focus on Function Helps Identify the Changes That Made Us Human
As humans, we are constantly evolving and adapting to our environment. Our ability to think, reason, and communicate sets us apart from other species. But what exactly makes us human? Scientists have been studying this question for years, and new research suggests that focusing on function may hold the key to identifying the changes that made us human.
The Importance of Function
Function refers to the purpose or role of a particular trait or behavior. In the case of humans, our unique traits and behaviors have evolved over time to serve specific functions that have helped us survive and thrive in our environment.
The Evolution of Human Traits
One of the most significant changes that made us human is our ability to walk upright on two legs. This trait allowed early humans to cover greater distances and access new food sources. It also freed up our hands for tool use and other tasks.
Another important change was the development of a larger brain. This allowed for more complex thinking and communication, which in turn led to the development of language and culture.
Studying Function in Fossils
To better understand how these changes occurred, scientists study fossils of early humans and their ancestors. By examining the structure and function of bones, teeth, and other body parts, they can make inferences about how these individuals lived and what challenges they faced.
For example, a recent study published in Science Advances looked at the shape of the inner ear in early hominins. The researchers found that changes in this area were likely related to an increased ability to hear high-frequency sounds, which would have been useful for communication and detecting predators.
Using Technology to Study Function
In addition to studying fossils, scientists are also using technology to better understand how early humans lived. For example, researchers can use computer simulations to model how different body shapes would have affected movement and energy expenditure.
This type of research has led to some surprising findings. For example, a study published in Nature Communications found that early humans may have been better adapted to running than walking. This suggests that our ability to walk upright may have developed later in our evolution.
Implications for Understanding Human Evolution
By focusing on function, scientists are gaining new insights into the changes that made us human. This research has important implications for understanding not only our past, but also our present and future.
For example, by studying how early humans adapted to their environment, we can gain a better understanding of how we can adapt to modern challenges such as climate change and urbanization.
Conclusion
In conclusion, focusing on function is helping scientists identify the changes that made us human. By studying the purpose and role of different traits and behaviors, researchers are gaining new insights into how early humans lived and evolved. This research has important implications for understanding our past and present, as well as shaping our future.
